CONFIGURATIONS

NOTES

1. Wiring for each zone can either be

Class A or Class B.

2. All output circuits are power limited

3. Electrical Ratings:

Output Zone Supervisory:

4mA max @ 24VDC

Output Zone Alarm:

4A max @ 24VDC

4. EOL resistor , 24k ohms ,

1 watt , 5%, (comes with module

package)

EOL-Kit S24135-D55-A1

5. Polarity shown in active state.

6. Maximum line resistance is

dependent upon the maximum

current draw of connected

notification appliances when

activated. The field wiring

resistance cannot exceed the

maximum line resistance specified

for any given NAC current draw.

(See Table)

Current Draw

Max Line Resistance

Example 2: If a ZIC-4AC has the following ZICCkt setting:

ZICCkt#1 - Strobe Unsync., Class A

ZICCkt#2 - Strobe Sync., Class A

ZICCkt#3 - Strobe Sync., Class B

ZICCkt#4 - not used

Maximum Backplane Current =

89 + (17 + 6) + (17 + 6) + (17 + 0) + (0 + 0) = 152mA

The ZIC-4A C zones can be configured for the following usages (Refer to

Figures 5 - 8):
